Chapter 57
Chapter 57. Three new and two different
There was a buzzing sound, like enlightenment.

Upon hearing the words iron money and tin money, everyone in the Nine Families immediately understood why Ren Ping was able to distinguish the chronology in such a short period of time.

In the history of ancient Chinese coins, the coins of the Song Dynasty are quite special.

On the one hand, it is because of the large amount of casting, and on the other hand, it is because not only copper, but also iron and tin in different proportions are contained in many coins.

This has its own special historical background.

In the Song Dynasty, especially the Southern Song Dynasty, the military was weak, and there were many strong enemies such as the Jin Kingdom and Xixia in the north. They not only attacked each other, but also traded frequently with each other.

At that time, copper was still a precious precious metal. In addition to copper coins, it was also used to cast weapons. In order to prevent the country’s copper coins from flowing out to enemy countries in commercial trade and indirectly funding their military forces, the Southern Song Dynasty court deliberately reduced the copper content in currency casting. iron and tin.

Over time, this kind of iron-containing and tin-containing coins entered the market and circulated together with pure copper coins. Especially in the land bordering the Kingdom of Jin and Xixia, iron-containing coins and tin-containing coins accounted for a large proportion, far surpassing copper coins. It has become a big exception in the history of Chinese currency.

These historical materials are recorded in many historical books. The proportion of iron and tin contained in copper coins will also change from time to time, corresponding to different years, and has nothing to do with the dynasty and year, so Ren Ping can figure it out.

After trying to understand the joints, the Nine Great Masters and the others all heaved a sigh of relief.

The difference between copper coins and iron coins and tin coins is not small. The weight is the same thing, but details such as rust stains and handles are also obviously different. Many ancient coin experts can tell the difference.

It seems that they overestimated that kid just now. Although it is not easy to have such a superb skill at such a young age, it is far less amazing than "weighing coins and dating generations".

Especially Qi Heng and Qiu Ming, just now, they almost thought that Ren Ping might be the son of a famous ancient coin master, and if he could really date coins, he might be a member of the National Ancient Spring Association.

fortunately……

"What iron money, tin money, these are obviously copper coins!"

At this time, Kang Yan was still at a loss, and with his level of ancient coins being less than half a bottle, he didn't know these historical materials at all, and thought that Ren Ping was playing tricks.

Now I felt more confident and laughed loudly:

"Mr. Qi, everyone, do you think this kid is funny? As we all know, in ancient China, copper was the precious metal, so when copper is used to make money, how can there be iron and tin?"

"I told you a long time ago that You Shengxing is not worthy of joining the Spring and Autumn League. They—"

"go out!"

With a sharp shout, Qi Heng couldn't bear it anymore and directly issued an order to expel the guests.

It was Qi Taixing who agreed with Jia Qiaoxing to write the first question, but who would have expected...

The idiot!It's fine to pick Song money, which is a big commodity, but why did you pick money containing iron and tin?Isn't this giving people points?
How can he hold on to his old face!
"What? Mr. Qi... you mean me?"

Kang Yan, who was frightened by Qi Heng's sharp shout, was completely at a loss. He looked at the Qingyuan Tongbao on the table, then at Ren Ping and Qi Heng, with a look of disbelief on his face:

"Is there really any iron money or tin money?"

"Don't hurry up!"

Qi Heng said viciously again, without showing any mercy.

Even now, he also knows that the more he talks, the more he will lose face, so he doesn't even bother to explain.

Kang Yan's face was blue and red, twisted and hideous several times in an instant.

After all, he is the leader of the line. Even if the strength of Jia Qiaoxing is not as good as the nine masters, he is highly respected in the industry, but who would have expected that he would be humiliated today!
It's a pity, no matter what, I dare not become an enemy of the Spring and Autumn League, so I endured the humiliation and looked around.

Seeing this, a middle-aged woman from the Nine Families sneered:
"Mr. Kang, when you go back, you should make up more lessons. Even if you enter the Spring and Autumn League, don't slack off. Otherwise, we can't afford to lose this person."

Kang Yan didn't say a word, his body trembled, he turned his head and walked away.

"Wait, take your things away."

At this moment, Ren Ping also spoke, and saw that he copied the five Qingyuan Tongbao on the table horizontally with his left hand, and then threw them over.

Amidst the jingling sound, the five copper coins bounced wildly at Kang Yan's feet, and then fell to the ground.

Kang Yan's face darkened:
"What are you doing? I don't want it anymore. I'll buy you candy for you!"

"Don't dare. This kind of iron money and tin money will depreciate very quickly even in the Song Dynasty, let alone the present,"

Ren Ping smiled coldly:
"Speaking of which, Mr. Kang, thanks to the good old coins you picked, you helped a lot. What's the chronological order? I can even distinguish their casting areas, believe it or not? Like this one, it should come from Sichuan and Shaanxi, this one , there is a high probability that it is the two lakes, and this one..."

Kang Yan's face was livid, and amidst the bursts of sarcasm, he couldn't bear it anymore, slammed the door and left.

The atmosphere became a little awkward. After a while, Qi Heng snorted softly and ordered people to sweep away the copper coins on the ground.

"Okay, the first question is considered to be passed, and the second question will be solved by me, Qi Taixing."

As he spoke, he turned around slowly, took a seat, and took out a small black bag from his coat pocket.

This small bag is about the size of a tennis ball and is sewn with fine black silk threaded with gold. It looks very elegant at first glance.

As for the contents, no need to ask, they are also ancient coins.

I saw Qi Heng holding the bottom of the bag with his left hand, and gently pulling open the mouth of the bag with his right hand, as if he was afraid of damaging the ancient coins in it. on the table.

"Also five..."

Seeing the amount of ancient coins on the table, Ren Ping couldn't help being taken aback, thinking that he was going to take another exam to compete for the top five.

Immediately realized something was wrong.

These five ancient coins are not ordinary. Although they have round square holes and the same traditional shape, they are not round, the square holes are not square, and there are many defects around the corners, as if they were caused by years of wear and tear.

On closer inspection, it is not entirely true, as if it had been deliberately cut and damaged.

After seeing the inscription on it clearly, he was taken aback suddenly:
It turns out that these five copper coins are not Tongbao, but five baht, and, moreover, they are bad money among five baht coins!
China has thousands of years of currency culture, and copper coins are just one of them. In addition, there are banknotes, gold and silver coins, etc.

Copper coins can be roughly divided into two categories, one is Tongbao, and the other is five baht.

Tongbao is just like the five Qingyuan Tongbaos. The year name is recorded in the inscription on the front, and it must be recast every time the emperor is changed.

The five baht is different. Most of the five baht inscriptions are the same, that is, the word "five baht", which has nothing to do with the dynasty and year.

And because the five baht appeared earlier than Tongbao, usually from the pre-Qin period to the Sui and Tang Dynasties, the age is long, the currency system is chaotic, and the process changes, making it even more difficult to identify.

Nowadays, in the ancient spring world, there are many collections of Tongbao and few five bahts. On the one hand, it is because of the existence of the world, and on the other hand, it is also because the existing five bahts are relatively rough in craftsmanship and poorly preserved, which does not meet the aesthetics of most people.

However, only those who really understand Guquan know that five baht coins are an insurmountable obstacle in the collection of ancient coins. If there is no five baht in the collection, it is not enough to be called a spring friend.

Especially the bad money!

The reason why this kind of money is called "bad" is because of the war years, social turmoil, a large number of minted coins cutting corners, and poor quality. .

But now, when Qi Heng took action, he took out five!

After all, he is an expert, not a layman like Kang Yan...

Ren Ping admired secretly in his heart, he knew that the second question would be difficult to pass, but unexpectedly this surname Qi even moved out all the things from the bottom of the box.

These five five-baht coins were put on the market, and each of them started with a six-digit figure. It was really uncommon, and I am afraid that the contribution of the Koizumi Association was among them.

Staring at the gap on the table, Ren Ping glanced at Qiu Ming, who was watching the situation with an unfathomable expression.

When Ren Ping glanced at him, he seemed to sense it, and he glanced over at him with a sinister look on his face.

"Watch out, kid. My question is called 'Three New and Two Different'. If you can answer it, my surname is Qi's number one!"

With a low cry, Qi Heng was finally ready to place it, and gently pushed the five cheap coins forward.

At this moment, everyone present couldn't help being stunned:
Three new and two different, what is this topic?But never heard of it?

Both Ren Ping frowned, as if feeling embarrassed, then slowly relaxed and smiled:
"Three new and two different? Okay, I'm afraid there are only three people in Quan Nanling who can come up with this question."

"What? You know?"

Qi Heng's eyebrows jumped sharply.
